Answer:
Since 3⁵= 243 you can just multiply by 3 to find 3⁶
The pyramid formula:

The volume in this case would be:
1/3×7.9×4
=79/30×4
=10.5333...
≈10.5 m^3
So a triangle is always 180°.
If one angle is 90° then we can subtract that from the 180° to find out how much the other two will be.
180°-90°=90°
So the other two angles added together will have to equal 90°.
